Teleology in Science

by Max Andrews

Many scientists believe teleology involves human action. The role of necessity and contingency are vital. Phrases like, “In order to…” and “It just so happens that…” are contingencies.  Before proceeding I’ll make a quick distinction between metaphysics and epistemology. Metaphysics includes being and becoming. Each have respective higher and lower forms. Being’s higher form is beauty, justice, etc. The lower form is triangularity, humanity, etc. Becoming’s higher and lower are sensible things and images, respectively. Epistemology includes knowledge and opinion. Knowledge pertains to understanding and reasoning. Opinion refers to perception and imagination.

Teleology refers to final causation.  Aristotle’s science included four different causes: material, formal, efficient, and final. For instance, consider a marble statue of a man. The material cause is the stuff, the marble.  The formal cause is the whatness/sort, the statue.  The efficient cause is that which brings it into being, the sculptor.  The final cause is the end purpose, David.

Can teleology simply be an implication? Information has origin in mind but we know minds act in accordance to purpose, thus teleology is an implication and not a direct conclusion.  Natural causation cannot bring about directionality or intentionality. Many philosophers of science, i.e. Alex Rosenberg, want to get us as close to nomic necessity as possible. Simply put, many philosophers, including Rosenberg, believe efficient causation is not satisfying.

Necessitarian Theory and Why Logical Positivists Attempt to Avoid Nomic Necessity

by Max Andrews

The necessitarian states that there are metaphysical connections of necessity in the world that ground and explain the most fundamental regularities.  Necessitarian theorists usually use the word must to express this connection.[1]  Thus, NT maintains must-statements are not adequately captured by is-statements (must ≠ is, or certain facts are unaccounted for).[2]  Nomic necessity claims that it is difficult for mere regularity to account for certain counterfactual claims because what happens in the actual world do not themselves imply anything about what would have happened had things been different.[3]  If it is now true that Q occurs if P causally precedes Q then the necessitarian can adequately account for counterfactual claims.  Given the present antecedent condition of P at tn and P implies Q at tn and it was true that P implied Q at tn-1 then using P as an antecedent for R at hypothetical tn-1’ then R is true if P was a sufficient condition R at tn-1’. Thus, there is certainty in the truth of counterfactual claims.  However, counterfactuals allow for conflict between truth functional interpretation and ordinary language.  For instance, any counterfactual claim with the necessary condition having a false truth-value and the sufficient condition obtaining a truth-value that is true then the counterfactual claim will be invalid.

Why is supporting counterfactual conditionals a symptom of nomic necessity? I would ague that there must be a connection or relationship between the conditions.  Consider the argument, as modus ponens, that if the moon’s core is made of cheese then my desk is made from mahogany.  What relationship do these two conditions have?
